INTERPOLATION ALGORITHM AND ITS ERROR PREDICTION FOR THE PARALLEL MACHINE TOOLS

Abstract

Abstract: The NC interpolation algorithm for the parallel machine tools is investigated. The algorithm which can be implemented by two steps, i . e . the rough interpolation in the Cartesian space and the precise interpolation in the actuator space. The upper bound of the theoretical error due to the PVT algorithm in the precise interpolation and nonlinear mappling is analyzed. Analyzed. It concludes that this error is negligible provided that the machine operates at low and middle speed.

Key words: Error prediction, Interpolation, Parallel machine tools
